Shapes of CeO2 bare nanoparticles. Red, blue and green represent the {111}, {110}, and {100} CeO2 surfaces, respectively. The shapes of the nanoparticles are generated at a water partial pressure of 1 bar and 298 K. Each shape is characterized by a ratio of surfaces defined in numerical percentage ({100}:{110}:{111}). The label B defines a bare surface.
